In geometry, if 2 angles are congruent, then their corresponding sides are also congruent. So you can have 3x-5=2x+9 & solve for x. Then substitute that value into all the other expressions to get the measures of all 3 sides. From there, you can determine the type of triangle
Pemdas start with this then see how your answer comes out then you isolate a variable do that complete your math to get your answer, hope this helped!!
...so??? What do you need
To find the median, add up the frequency column to find how many trains there were in total. There were 44 trains in total in this grouped frequency table, so work out 44 + 1 2 = 45 2 = 22.5. The median is therefore between the 22nd and 23rd values.
